Characteristics
This manual lug carbon steel knife gate valve is cast from WCB carbon steel with high pressure and medium temperature resistance. Threaded lug structure supports single-side blind installation for pump ports and pipeline ends. Full straight bore avoids sludge and dust blockage. Equipped with simple manual handwheel for reliable cut-off, low failure rate and maintenance cost, widely used for steam, ash and non-corrosive slurry pipelines.
Advantages
- WCB carbon steel features high mechanical strength, withstands medium temperature and pressure without deformation, suitable for steam and high-temperature ash pipelines.
- Threaded lug design allows single-side blind installation, bears pipeline tension, easy to maintain, perfect for pump ports and pipeline ends.
- Simple manual handwheel structure with low failure rate, intuitive operation, minimal maintenance and cost-saving for general cut-off pipelines.
Packing
Standard export wooden case packaging
Application Scenarios
The WCB knife gate valve widely used in power plant ash and desulfurization pipelines, metallurgical slurry lines, heating steam pipes, building material dust conveying, non-corrosive industrial sewage and pump inlet/outlet cut-off systems.
